7. Maintenance
7.1. Care
The SM32 converters must be installed according to the relevant installation
regulations. They do not require any particular maintenance. They should not be
cleaned with a wet or moist cloth. The power supply must be switched off before
cleaning.
7.2. Service
The screws of all terminals on the device should be re-tightened two weeks after
initial commissioning. This should be repeated each year.
If inverters have been stored for more than three years, the capacitance of the
intermediate circuit capacitors may have been impaired. Before commissioning
these devices, it is advisable to regenerate the capacitors by connecting them
to the voltage for two hours with the inverter disabled. After these operations the
device is ready to be installed without limitations.
7.3. Repairs
Repairs of the device should only be carried out by the specialist personnel (quali-
fied by the manufacturer).
7.4. Customer Service
For customer service, please contact your Gefran office.
7.5. Disposal: WEEE information
Attention ! Please dispose of this unit with care as an industrial waste and accor-
ding to your required local regulations.

The symbol showing a crossed-out wheeled bin on equipment or its packaging
indicates that the product must be collected separately from other waste at the
end of its useful life.
The manufacturer is responsible for organising and managing the separate collec-
tion of this piece of equipment at the end of its useful life.
Users wishing to dispose of the equipment must therefore contact the manufactu-
rer to obtain instructions from the same on how to have the equipment collected
separately at the end of its useful life.
By collecting the disused equipment separately, it can be recycled, treated or
disposed of in an environmentally friendly manner, thus helping to prevent the
environment and public health from being affected negatively and enabling reuse
and/or recycling of the materials forming the same equipment.
